Accident analysts. A 1500 kg sedan goes through a wide intersection traveling from north to south when it is hit by a 2200 kg SUV traveling from east to west. The two cars become enmeshed due to the impact and slide as one thereafter. On-the-scene measurements show that the coefficient of kinetic friction between the tires of these cars and the pavement is 0.75, and the cars slide to a half at a point 5.39 m west and 6.43 m south of the impact point. How fast was each car traveling just before the collision?

- You have been called to testify as an expert witness in a trial involving a head-on collision. Car A weighs 1515 lb and was traveling eastward. Car B weighs 1125 lb and was traveling westward at 43.0 mph. The cars locked bumpers and slid castward with their wheels locked for 18.5 ft before stopping. You have measured the coefficient of kinetic friction between the tires and the pavement to be 0.750. What speed (in miles per hour) was car A traveling just before the collision?

Suppose a 140 g baseball traveling at 40 m/s strikes your head at an angle of 20 degrees from the horizontal. The forehead can undergo a displacement of roughly about 0.75mm before a fracture and the cheekbone only about 0.2mm. What is the magnitude of the force that stops the baseball? What force does the baseball exert on your head? Explain. Are you in danger of a fracture if the ball hits you in the forehead? On the cheek? What is the time interval necessary for either the forehead or cheek bone to break based on the forces stated?arrow_forwardHi please help with the following: After hitting a long fly ball that goes over the right fielder's head and lands in the outfield, the batter decides to keep going past second base and try for third base. The 59 kg player begins sliding 3.40 m from the base with a speed of 4.35 m/s. If the player comes to rest at third base, what was the coefficient of kinetic friction between the player and the ground?arrow_forward

You have a quick reaction time of 0.60 seconds before applying the brakes which slow your car for 2.36 seconds before you enter a skid. Your car then skids for 39.4 m before coming to a stop. Assuming a coefficient of kinetic friction between the tires and the road of 0.45, find (a) the acceleration rate you had while the brakes were applied prior to the skid, (b) the total distance the car traveled from the moment the deer jumped to when the car stopped, (c) the work done by the brakes, and the work done by friction during the skid.arrow_forwardA 6-g bullet is shot into a 2.1-kg block of wood, where it becomes embedded. The block is initially at rest and the bullet has an initial velocity of 400 m/s. The block then travels 1.2 m horizontally.

- A 2.50 kg box sits halfway up a 16.0 m long ramp that is inclined at an angle of 16.00. You shove a second box, of mass 1.50 kg, that's at the bottom of the ramp, so that it starts sliding up the ramp with a speed of 20.0 m/s. It hits the first box, sticks to it, and they both continue to slide up the ramp. The coefficient of kinetic friction between the boxes and the ramp is 0.200. Where, from the bottom of the ramp, do they come to rest?arrow_forwardThe coefficient of friction between the wheels of Yamaha motorcycle and the dry pavement is 0.79. An animal walks out into the road, causing a motorcyclist to slam on the brakes. The wheels stop turning, but the tires skid along the road, causing intense friction and heat. Determine the magnitude (positive) of the acceleration which the 217-kg motorcycle experiences while skidding to a stop. The mass includes the rider. Answer: m/s/s (or m/s²)arrow_forwardAt the scene of an accident, two traffic experts appear to determine which of the drivers was at fault considering that it was a highway where the speed limit is 80 km / h. The data collected in the field indicate that the vehicles stuck and skidded together a length of 25 m on the pavement whose dynamic friction coefficient is μk = 0.30. Considering that the masses of vehicles A and B are 2300 kg and 1500 kg, respectively, specify which of the cars was speeding at the moment of impact and by how much it exceeded the speed limit. Express your result in km / h for the purposes of the expertise.arrow_forward
